Answer:
5z^3 * (42) (please tell me if it is correct or not)
sqrt (z) * sqrt (30z^2) * sqrt (35z^3)
z*30z^2 = 30z^3
30z^3 * 35z^3 = 1050z^6
now we have sqrt(1050z^6
we can simplify z to (z^2)^3)
sqrt (1050 * (z^2)^3)
The biggest square in 1050 is 25 which is 5^2. 25 times 42 = 1050
5^2 * 42 * (z ^2)^3
we see two perfect squares, 5^2 and z^2^3
the sqrt of 5^2 = 5
5 * sqrt (42 * (z ^ 2 )^ 3)
the sqrt of z^2^3 = z^3
5z^3 * (42)
we cannot simplify this further.
